The molding structure can protect the pin from being damaged in a molding process so as to meet a requirement on consistency in batch production, is simple and practical in equipment, convenient to operate, and favorable for reducing the production cost and increasing the production efficiency.
Description
Technical field
The utility model relates to a kind of mounting structure, especially relates to a kind of molding structure of the MOSFET of being used for power tube pin.
Background technology
The MOSFET power tube is applied to medical power amplification system, realizes power amplification; MOSFET power tube pin is a strip, and is parallel with installed surface; But in certain medical power amplification system, because the structure and layout restriction requires MOSFET power tube pin to be shaped to certain given shape, to satisfy installation requirement! Traditional clubfoot frock does not realize that the power tube pin by the preliminary dimension moulding, can not satisfy the uniformity in the batch process, and causes pin damaged in moulding easily.
The utility model content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art; A kind of molding structure of the MOSFET of being used for power tube pin is provided, and this molding structure can protect pin injury-free in moulding, satisfies the uniformity in producing in batches; And install simple and practical; Easy to operate, reduced production cost, improved production efficiency.
The purpose of the utility model realizes through following technical proposals: be used for the molding structure of MOSFET power tube pin, comprise base, said base is provided with location structure, and said location structure top is provided with forming blocks.
Be provided with briquetting between said location structure and the forming blocks, said briquetting is fixed on the forming blocks.
The sidewall of said forming blocks is provided with the patrix edge of a knife, and the sidewall of said location structure is provided with the counterdie edge of a knife, and the sidewall of the said patrix edge of a knife and the counterdie edge of a knife is in same vertical plane.
The said patrix edge of a knife and the counterdie edge of a knife all adopt mould steel to process.
Said briquetting adopts plastics or brass to process.
Said location structure and forming blocks all adopt brass to process.
In sum, the beneficial effect of the utility model is: this molding structure can protect pin injury-free in moulding, the uniformity in satisfy producing in batches, and install simple and practically, easy to operate, and reduced production cost, improved production efficiency.
Description of drawings
Fig. 1 be the utility model cut the leg structure sketch map;
Fig. 2 is the first molding structure sketch map of the utility model;
Fig. 3 is the final molding structural representation of the utility model.
Mark and corresponding parts title in the accompanying drawing: 1-forming blocks; 2-briquetting; 3-location structure; 4-base; 5-counterdie edge of a knife; 6-patrix edge of a knife.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, be used for the molding structure of MOSFET power tube pin, comprise base 4, said base 4 is provided with location structure 3, and said location structure 3 tops are provided with forming blocks 1.
Be provided with briquetting 2 between said location structure 3 and the forming blocks 1, said briquetting 2 is fixed on the forming blocks 1.
The sidewall of said forming blocks 1 is provided with the patrix edge of a knife 6, and the sidewall of said location structure 3 is provided with the counterdie edge of a knife 5, and the sidewall of the said patrix edge of a knife 6 and the counterdie edge of a knife 5 is in same vertical plane.
The said patrix edge of a knife 6 all adopts mould steel to process with the counterdie edge of a knife 5.
Said briquetting 2 adopts plastics or brass to process.
Said location structure 3 all adopts brass to process with forming blocks 1.The said patrix edge of a knife 6 and the counterdie edge of a knife 5 adopt the HRC hardness greater than 40 mould steel, and briquetting 2 adopts plastics or brass, and location structure 3 adopts brass with forming blocks 1, and electroplating processes need be carried out with antirust in its surface of all metal materials.
MOSFET is metal-oxide layer-semiconductor-field-effect transistor, is called for short metal-oxide half field effect transistor, is a kind of field-effect transistor that can be widely used in analog circuit and digital circuit.
Divided for three steps realized that the first step realized cutting pin the frock of MOSFET power tube pin moulding, second step was accomplished first moulding, and the 3rd step was accomplished final molding; The implementation that the first step is cut pin is: through calculating and engineering experience confirms that pin cuts pin length; The placement positioning structure 3 of cutting pin frock base 4 design MOSFET power tubes with cut the underfooting mould edge of a knife 5; Cutting the pin frock patrix correspondence position design briquetting 2 and the patrix edge of a knife 6; Power tube is easily put into predeterminated position, and patrix moves from top to down, and patrix briquetting 2 at first compresses the MOSFET power tube; Then the patrix edge of a knife 6 forms Y direction shearing force segment MOSFET power tube pin with the counterdie edge of a knife 5, and the pin length that is retained on the MOSFET power tube meets design requirement; The implementation of the second first moulding of step is: in the placement positioning structure 3 and forming blocks 1 of moulding frock base 4 design MOSFET power tubes; In moulding frock patrix correspondence position design briquetting 2 and forming blocks 1; Power tube is easily put into predeterminated position; Patrix moves from top to down, and patrix briquetting 2 at first compresses the MOSFET power tube, and then patrix forming blocks 1 is pressed in and makes the moulding of MOSFET power tube pin on the counterdie forming blocks 1; The implementation of the 3rd step final molding is: in the placement positioning structure 3 and the forming blocks 1 of moulding frock base designs MOSFET power tube; In moulding frock patrix correspondence position design briquetting 2 and forming blocks 1; Power tube is easily put into predeterminated position; Patrix moves from top to down, and the briquetting of patrix briquetting 2 and forming blocks 1 at first compresses the MOSFET power tube, and then patrix briquetting 2 and forming blocks 1 in the forming blocks 1 are pressed in and make MOSFET power tube pin final molding on the counterdie forming blocks 1.
Take aforesaid way, just can realize the utility model preferably.
